I am wondering if it is possible to compute the execution time using tic and toc statement but eliminating printing time?
I have a big program ... and it has a lot of printing statements in the middle ...
Is it possible to count the time without the time consumed by printing? or should I stop each printing statement one by one?

Do you mean you have lots of disp( ) or fprintf( ) etc. statements, but want to somehow not count them in the timing results?

You can just save the value in a variable
timerValue = tic;
% something very useful to do
tstop = toc(timerValue);

ok, sorry...
Count the time for printf wit tic/toc like I said and subctract the value from the time of computation

You could also try to shadow the fprintf function, but that is a dangerous business.
